CBSEyeAlert: due to live NCAA basketball Sunday, the start time for The Amazing Race could be delayed East/Central Zones ONLY. Check here for updates!

apskip:
The NCAA Sunday later game for the New York metro area (and I bet for much of the nation) is North Carolina vs. Kansas, with tipoff scheduled for 515pm pm. That means we could expect about a 715pm start time for 60 Minutes. However, these things could delay it:1. an overtime for the prior CBS game at 245pm (Indiana vs. Temple)2. overtime for North Carolina vs. Kansas3. a CBS decision to also televise the ending of another game (note- this is unlikely to occur since the only other game in progress then will be Minnesota vs. Florida on TNT)

Jimmer:
apskip,

A delay in the Indiana/Temple game will not cause a delay for the North Carolina/Kansas game because they are being held in different arenas. (Indiana/Temple is in Dayton, UNC/Kansas is in Kansas City)

Therefore, the only things that will delay 60 minutes are scenarios 2 or 3 you had listed. Scenario 1 will not cause a delay in the CBS lineup.
